SUPPORTING AND PRESERVING TELEGRAPHIC CO'NDUCTORS.

SPECIFICATION forming part of Letters Patent No. 275,195, dated April 3, 1883,

Application filed October Q7, 1882. (No model.)

To all whom it may concern.-

Be it known that l, JAMES H. GREEN, of Brooklyn, in Kings county, and State ot' New York, have invented a new and useful lmprovementin Supporting and Preserving Telegraphic Conductors, of which the following is a speciiication.

The object ofthe presentimprovement is to provide for riddin g telegraphic conductors ot' moisture when they are laid or arranged in conduits.

To this end the improvement consists in the combination, with a box, trough, or pipe, telegraphic conductors arranged therein, and supports for the telegraphic conductors, provided with openings, of means whereby air may be caused to circulate through the box, trough, or pipe.

The improvement also consists in the combination, with a number of telegraphic conductors, of a box, trough, or pipe containing the said conductors, a number of supports for the said conductors, arranged within the box or trough or pipe, openings lbeing providedin the supports and between the supports and the box or trough or pipe for the circulation ot' air, and. means whereby air may be caused to circulate through said bex, trough, or pipe.

The improvement also consists in the combination, with awooden box or trough adapted to contain telegraphic conductors, blocks constituting supports for the telegraphic conductors, and provided with openings for the passage ot' air, of an outer box or trough and a layer of pitch or analogous material between lthe boxes or troughs.

The improvement also consists in the combination, with a wooden box or trough adapted to contain telegraphic conductors, blocks constituting supports for the telegraphic conductors, and provided with openings for the passage of air, of an outer box or trough, a layer of pitch or analogous material between the boxes or troughs, and al layer ot' pitch or analogous material on the exterior ot' the outer box or trough.

The improvement also consists in the ccmbination, with a box, trough, or pipe, tele graphic conductors arranged therein, and supports for the telegraphic conductors, provided with openings for the passage of air, of means for causing air to circulate through the box, trough, or pipe, and means i'or drying the air beforeitsentranceintothe box, trough, or pipe.

In the accompanying drawings, Figure l is a longitudinal section otan apparatus embodying my improvement, and Fig. 2 Ais a transverse section of the same.

Similar letters ot reference designate corresponding parts in both iigurcs.

A designates a box, trough, or pipe, which may be made oi" wood and of a square crosssection. At suitable intervals it is provided with blocks B, which may be made of wood or other suitable material. These blocks are perforated so as to receive and support telegraphic conductors C. rlhe said blocks are arranged sutliciently near together to prevent the tele graphic conductors from accidentally touching each other. -As shown, the corners of the blocks are cut oft' so as to leave spaces a, through which air may pass. The blocks are also provided with central openings, l), which likewise afford provision for the circulation of air past them. The box, trough, or pipe A is inclosed in a larger box, trough, or pipe, D, which may be of the same material and construction. A layer of pitch or analogous material, E, is interposed between the two boxes, troughs, or pipes A D, and a layer of like material, G, is applied to the exterior of the box, trough, or pipe. The box, trough, or pipe A is practically water-proof and moistureproot'. In order to prevent the moisture in the atmosphere from condensing' within this box, trough, or pipe, or the collection of moisture there from any source, l circulate air through the same, either constantly or at desired intervals. Any suitable means may be employed for this purpose-as, for instance, a pump or blower; but I prefer generally to employ a chimney, stack, or tlue. I have shown a chimney, H, communicating with the box, trough, or pipe A for this purpose. This inducesa circulation ol' air through the pipe from the other end. A tire, lamp, or other source of heat will be kept in the chimney to induce or stimulate an upward draft. in lieu of or in addition to this, a cap or cowl may be employed to induceor stimulate an upward draft. In many cases a chimney connected with a furnace used for manufacturing purposes or some industry can IOO be utilized for inducing a draft through the box, trough, or pipe A. If the atmosphere is moist, as it is continuously in many places and at times in all places, I shall preferably dry the air before circulating it through the box, trough, or pipe A. This may be done by chemicals or by heat. I have shown aturnace, l, for heating it. The air passes through this furnace, and is heated and dried before entering the box, trough, or pipe A. The air may be dried by cooling' it before its entrance into the box, trough, or pipe A.

This improvement is particularly designed i'or telegraphic conductors to be laid under ground.

That I claim as my invention, and desire to secure by Letters Patent, is-

l. rlhe combination, with a box, trough, or pipe, telegraphic conductors arranged therein, and supports for the. teleoraphic conductors, provided with openings, ot means whereby air may be caused to circulatethrough the box, trough, or pipe, substantially as specified.

2. The combination, with a number of telegraphic conductors, of a box, trough, or pipe containing the said conductors, a number of supports for the said conductors, arranged within the box or trough or pipe, openings being provided in the supports and between the supports and the box or trough or pipe for the circulation ot' air, and means whereby air may be caused to circulate through the box, trough, or pipe, substantially as specified.

3. The combination, with a wooden box or trough adapted to contain telegraphic conductors, blocks constituting` supports for the telegrapliic conductors, and provided with openings for the passage of air, of an outer box or trough and a laye-r of pitch or analogous material between the boxes or troughs, substantially as specified.

#la The combination, with a Wooden box or trough adapted to contain telcgraphiceonductors, blocks constituting supports for the telegraphic conductors, and provided with openings for the passage of air, ot' an outer box or trough, a layer of pitch or analogous material between the boxes or troughs, and a layer of pitch or analogous material on the exterior of the outer box or trough, substantially as specilied.

5. The combination, with a box, trough, or pipe, telegraphic conductors arranged therein, and supports for the telegraphic conductors, provided with openings t'or the passage ot' air, ot' means tor causing air to circulate through the box, trough, or pipe, and means l'or drying the air bet'ore its entrance into the box, trough, or pipe, substantially as specified.
